Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a timepiece pointer mounting structure for attaching pointers such as the hour hand to a pointer pipe in a timepiece equipped with at least an hour hand and a minute hand.

(Prior Art) Conventionally, as shown in FIG.
It is known that each pointer is provided with a cylindrical protrusion 14 in order to fit and attach to the tip of the pointer 2a. These cylindrical protrusions 14 were provided so as to all face toward the watch glass 16 side or the opposite movement side (in the illustrated example, the movement side) as shown in the figure.

However, according to this conventional timepiece hand mounting structure, all the cylindrical protrusions of the hands are provided in one direction, so the hour hand 2 is particularly restricted on the movement side (upper side in the figure) as shown. As a result, the distance l between the clock 2 and the minute hand 4 becomes narrower, and there is a risk that the tip of the clock 2 may come into contact with the minute hand 4.There is also a limit to the length of the pointer that can be attached, and as a result, for example, a wall clock with a long pointer, etc. The disadvantage was that it was difficult to apply.

(Purpose of the invention) Therefore, the purpose of the invention is to solve the above-mentioned conventional drawbacks and to provide a watch equipped with at least an hour hand and a minute hand without changing the distance between the dial and the glass. To provide a timepiece pointer mounting structure having a simple structure and allowing a long pointer to be attached by increasing the distance from the minute hand.

(Structure of the invention) Therefore, in order to achieve the above-mentioned purpose, the present invention provides the hour hand and the minute hand with cylindrical protrusions that protrude in one direction, and these cylindrical protrusions are fitted to the tip of each pointer pipe. In the pointer mounting structure of a timepiece, a cylindrical protrusion of the minute hand is provided to protrude toward the movement side, and a cylindrical protrusion of the hour hand is provided to protrude toward the minute hand side to fit into the pointer pipe. It is a feature.

(Example) Hereinafter, the present invention will be described in detail based on an example of the present invention shown in the drawings.

FIG. 2 is a sectional view of the main part of the central part of the watch showing the pointer attachment structure of the present invention. In the figure, reference numeral 20 indicates a watch glass, and reference numeral 22 indicates a dial. A minute hand 28 is fitted to the tip of a minute hand pipe 26 of a minute wheel 24 located in the center of the figure. This minute hand is provided with a cylindrical protrusion 30 facing toward the movement side (upper side in the figure). The minute hand 28 is attached by fitting the tip of the minute hand pipe 26 into the cylindrical protrusion 30 thereof.

An hour hand wheel 32 is attached to the outside of the minute hand pipe 26. An hour hand 36 is attached to the tip of an hour hand pipe 34 of this hour wheel 32. The hour hand 36 is provided with a cylindrical protrusion 38 into which the tip of the hour hand pipe 34 is fitted. The cylindrical protrusion 38 of the hour hand 36 protrudes toward the minute hand 28 and faces the cylindrical protrusion 30 of the minute hand 28 . in this way,
Since the cylindrical protrusion 38 of the hour hand 36 is housed in the space between the hour hand 36 and the minute hand 28, the distance L between the hour hand 36 and the minute hand 28 is the first as shown in FIG.
This is ensured to be significantly larger than the conventional spacing l shown in the figure.

In addition, in the embodiment shown in FIG. 2, an example of a two-hand type watch with an hour hand 36 and a minute hand 28 has been explained, but the present invention can also be applied to a three-hand type watch with an indicator hand, etc. Of course.

(Effects of the invention) According to the invention, the cylindrical protrusions protruding from the hour and minute hands are opposed and fitted into each pointer pipe, so the distance between the dial and the glass is the same as before. This makes it possible to secure a wide gap between the hour hand and minute hand, which prevents the two hands from touching each other, making it possible to install even relatively long hands, making it ideal for table clocks and wall clocks. It is useful for.

Further, according to the present invention, when attaching the hour hand to the hour hand pipe, the cylindrical protrusion provided on the hour hand can be held and fitted to the hour hand pipe, so there is an effect that automation is easy.
